The Market Segment Specialization Program focuses on developing highly trained examiners for a particular market segment. A market segment may be an industry such as construction or entertainment, a profession like attorneys or real estate agents or an issue like passive activity losses. An integral part of the approach used is the development and publication of Audit Techniques Guides. These Guides contain examination techniques, common and unique industry issues, business practices, industry terminology and other information to assist examiners in performing examinations.
